Pipe presser for vinyl house {Tools for pipe connection of vinyl house}

The present invention relates to a pipe compactor for greenhouses, and more particularly, to improve the pipe compactor so that the user can adjust the grip force to hold and press the compactor with both hands according to the user, thereby providing convenience in use and handling. Of course, it relates to a pipe compactor for a greenhouse that allows the pipe compression joint work to be performed more easily by making it easy to grasp the degree of pressing force by closing the compactor.

In general, a vinyl house is a structure built by fixing the bottom of a pipe that becomes a frame in a round arch shape to the ground, weaving pipes in a transverse direction, and covering the outside with vinyl.

When installing a vinyl house, the pipe is used to produce a support that is covered with vinyl. These pipes are cut to a certain length and connected to a required length to form an intended post.

In connecting such a pipe for a vinyl house, conventionally, a fixing screw is used or the pipe is extended and fixed by usage.

The pipe joint has been made by inserting a sleeve into the inner diameter of each pipe to be connected, drilling a hole from the outside of the pipe, and then fastening a screw to the drilled hole.

In the above method, it is necessary to form a screw hole at an exact position on the outer diameter of a pipe having a round diameter, but it is quite difficult to directly fasten the fixing screw to the round outer circumferential surface of the pipe using an electric drill.

This conventional pipe fixing method is not efficient, so it is very difficult for unskilled people, and a considerable difference in working time occurs depending on the skill level of using an electric drill.

In order to solve the above problems, recently, a method of interconnecting pipes using a pipe compactor has been used.

Looking at the structure of a conventional pipe compactor, Republic of Korea Utility Model Registration No. 20-0236337 (name: compactor for connecting vinyl greenhouse pipes, registration date: June 18, 2001, hereinafter referred to as 'patent document') is disclosed. .

As shown in FIGS. 1 and 2, the press for pipe connection in the above patent document has a handle (1) (1a), a rotary link (2) (2a), and a pressurizer (3) (3a). ), it consists of a fixing member (4) and a supporting member (5).

The handle (1) (1a) is made of synthetic resin at one end so that the operator can hold the work by hand and has a gripping part (6) (6a) formed with a protrusion. It is fixed by the first fixed shaft 7, and the rotating link 2 (2a) is also rotatably fixed to the outside of the fixed shaft 7.

The rotating link (2) (2a) is rotatably fixed with the handle (1) (1a) and the second fixing shaft (8) (8a), and the other side is coupled with the pressing member (3) (3a). A holder (9) (9a) is formed as a cylindrical body in which a female screw is formed so that the holder (9) (9a) is rotatable in a state of meshing with gears formed on opposing surfaces so that the holder (9) (9a) can always maintain a constant distance. The fixing member 4 is fixed by the third fixing shaft 10 (10a).

The fixing member 4 fixes the rotating links 2 and 2a with two third fixing shafts 10 (10a) so that both ends of the rotating links 2 and 2a turn in a direction closer to or away from each other. and a female screw part 11 is formed from the center of one side to fix the support member 5.

The support member 5 is composed of a bolt having a male screw part 12 formed thereon and fastened to the female screw part 11. It serves to anchor the pipe. The pressurizer (3) (3a) is made of a metal material that is harder than the material of the pipe, such as carbon tool steel, and has one end protruding sharply to pressurize the pipe, and a male screw is formed to fasten to the holder (9) (9a) It is detachably fixed so that it can be exchanged or the tip polished.

The pressing part (3) (3a) appropriately rotates the support member (5) so that when the pipe is seated on the head of the support member (5), the portion forming the maximum diameter of the pipe is the holder (9) (9a) The pipe connection work is carried out in a state in which it is aligned with the pointed end of the pressurizing part (3) (3a) fixed to. That is, when the operator holds the grippers 6 and 6a with their hands and pulls them outward, the ends where the second fixing shafts 8 and 8a are fixed around the first fixing shaft 7 move in the direction of getting closer to each other. At this time, since the rotating link (2) (2a) is fixed to the third fixing shaft (10 (10a) of the fixing member (4), the ends where the holder (9) (9a) is formed turn in a direction away from each other. do.

In this state, when the pipe (P) is placed on the head of the support member (5) and the handle (1) (1a) is operated in the direction of approaching, it operates in the opposite direction this time around the first fixed shaft (7) While the second fixing shaft (8) (8a) rotates in a direction away from each other, the holder (9) (9a) rotates in a direction closer to each other, so that the sharp tip of the pressing member (3) (3a) presses the pipe, as shown in FIG. As in, the pipe (P) and the sleeve (S) are connected and fixed to each other by forming a groove (20) while pressing the sleeve (S) therein together.

In the operation of processing a groove in the pipe by opening and closing the handle in the above manner, in particular, force (grip force) must be applied with the handles corresponding to each other in the initial stage of the closing operation. However, this is because the swinging motion of the handle that presses the pressurizer with the sharp end differs from user to user, so not only is this motion very unnatural, but also there are not a few cases where more force is applied depending on the angle of closing the handle, which increases fatigue. Disadvantages are pointed out.
